Abstract

The paper considers beams in the form of geometric progression of optical vortices. Numerical modelling of the propagation of such optical fields in turbulent media is simulated using the Fresnel integral. The topological charges of the initial and resulting fields have been calculated. As expected, the analysis of the obtained results showed that superpositions with a smaller number of beams are more resistant to distortions by strongly turbulent media. However, in the case of a superposition in the form of a geometric progression with a parameter, the stability of beam propagation is affected not only by the medium parameters, but also by the parameters of the superposition.

大气湍流对光学涡旋叠加拓扑电荷的影响
本文以光涡旋几何级数的形式考虑光束。利用菲涅耳积分模拟了这种光场在湍流介质中的传播。计算了初始场和结果场的拓扑电荷。正如预期的那样,对得到的结果的分析表明,光束数量较少的叠加态更能抵抗强湍流介质的畸变。然而,在具有参数的几何级数形式的叠加情况下,光束传播的稳定性不仅受介质参数的影响,而且受叠加参数的影响。

期刊介绍: The journal covers a wide range of issues in information optics such as optical memory, mechanisms for optical data recording and processing, photosensitive materials, optical, optoelectronic and holographic nanostructures, and many other related topics. Papers on memory systems using holographic and biological structures and concepts of brain operation are also included. The journal pays particular attention to research in the field of neural net systems that may lead to a new generation of computional technologies by endowing them with intelligence.
